摘要： A technique is performed in a first device of a set of devices. The technique involves receiving a query message from a network node, the query message requesting data regarding a network resource. The technique further involves accessing an identifier which indicates whether the first device is in charge of the network resource, and providing a response message to the network node in response to the query message. The response message is provided after waiting a predefined amount of time when the identifier indicates that the first device is not in charge of the network resource and there is reason to believe another device of the set is operating. The response message is provided without waiting the predefined amount of time when the identifier indicates that the first device is in charge of the network resource. Moreover in some situations, the first device may choose to not respond.

摘要： A method performed by a DHCP server. The method involves receiving a transformation instruction from a user or other command source. The method further involves in response to receiving a request from a client for a network address, applying the transformation instruction to the client request to generate a client identity pattern; and assigning a network address from a pool of network addresses to the client based on the client identity pattern. Apparatus for use in practicing the method are also claimed.
摘要翻译：由DHCP服务器执行的方法。该方法涉及从用户或其他命令源接收变换指令。该方法进一步涉及响应于从客户端接收网络地址的请求，将转换指令应用于客户机请求以生成客户端标识模式; 以及基于客户端标识模式将网络地址池从网络地址池分配给客户端。还要求保护用于实施该方法的装置。

摘要： As a server device receives packets from a client device, the server device counts the number of packets received over a particular time interval and compares the result with a preset packet transmission threshold. When the number of packets received from the client device in the time period reaches or exceeds the packet threshold, the server device can detect a potential malfunction of the client device and as such, refrains from processing further packets from the client device. By rate limiting based upon the number of packets received from the client device over a given time interval, rather than on the bandwidth taken by the requests received from the client device, the server device can minimize monopolization of the server device's resources as caused by the packets received at a relatively low rate from a client device.
摘要翻译：当服务器设备从客户端设备接收数据包时，服务器设备对特定时间间隔内接收到的数据包数进行计数，并将结果与预设的数据包传输阈值进行比较。当在该时间段内从客户端设备接收到的分组数量达到或超过分组阈值时，服务器设备可以检测客户端设备的潜在故障，并且因此避免处理来自客户端设备的其他分组。通过基于在给定时间间隔内从客户端设备接收到的分组数量而不是从客户端设备接收到的请求采取的带宽的速率限制，服务器设备可以最小化服务器设备资源的垄断，这是由从客户端设备以相对低的速率接收的分组。
